Hydraulic Cylinder for Ex30 to Ex90 Mini Excavator Arm Boom Bucket Replacement

Product Specification

Product Description

Introducing our premier line of hydraulic cylinders engineered specifically for the Ex30, Ex45, Ex60, Ex65, Ex70, Ex75, Ex80, and Ex90 series of mini excavators. Designed to serve as direct replacements for arm, boom, and bucket operations, these cylinders are the cornerstone of your machine's power, precision, and productivity. Whether you are performing delicate grading work or heavy-duty digging, our hydraulic solutions provide the reliable force and control you need to get the job done efficiently and safely. We also offer customization options to meet your unique machinery specifications and performance requirements.

Crafted from superior-grade materials, each hydraulic cylinder is built for endurance and longevity in the most demanding construction environments. The cylinder barrel is manufactured from cold-drawn, honed steel tubing that ensures a smooth, low-friction surface for optimal seal life and consistent operation. The piston rod is precision-machined from induction-hardened, chrome-plated steel, providing exceptional resistance to bending, scratches, and corrosion. This robust construction ensures that our cylinders can withstand the high pressures and cyclical loads inherent in excavator work, from continuous digging and lifting to intricate attachment manipulations.

The performance of any hydraulic cylinder depends critically on its sealing system. Our cylinders incorporate an advanced, multi-lip sealing system designed to maintain pressure integrity and prevent both internal and external leaks. These seals are selected for their resilience to a wide range of hydraulic fluids and operating temperatures, ensuring reliable performance from the cold start of a winter morning to the heat of a long summer workday. The gland, piston, and rod seals work in concert to protect the hydraulic system from contaminants like dirt, dust, and moisture, which are major causes of premature component wear. Every cylinder undergoes rigorous pressure testing before shipment to certify its performance and structural integrity, giving you confidence in its operational readiness from day one.

These hydraulic rams are engineered for seamless integration with the specified mini excavator models. The mounting points, port configurations, and stroke lengths are dimensionally precise, guaranteeing a perfect fit that restores your equipment to its original operational standards without the need for modifications. This focus on exact specifications ensures that the cylinder will articulate correctly with the machine's linkages, providing the full range of motion required for arm extension, boom elevation, and bucket curling. By choosing our components, you minimize downtime and simplify the replacement process, allowing your fleet to maintain maximum uptime and operational efficiency. Trust in a component that delivers consistent power and precision for all your earthmoving and construction projects.
